As Sreekumar points out, you can't delete records from a CDS/ISIS
database when building "as is" (unless you edit the database in your
CDS/ISIS program). However, if you explode the database you get a ".nul"
file for each record, and you can just delete the ".nul" files for the
duplicate records. (Editing the collection archives isn't such a good
idea because they will be replaced when you next rebuild the collection).
